Hello Kumar, For JEE Mains and JEE Advanced, you have to study both 11th and 12th CBSE syllabus because most of the contents are linked to the previous topics so you cannot skip one of them or focus on just one. Also you have to secure good scores in boards too. This balance will help you to get a good percentile score at the end.
Good luck.
Thank you.
